Abstract

We report on continuous-wave lasing of Yb3+ at room temperature in the noncentrosymmetric RbTiOPO4 crystal, codoped with Nb5+, for all three possible polarizations. A maximum output power of 154mW at 1050nm was obtained for an absorbed power of 386mW. The highest slope efficiency reached 60% and the lowest threshold (with respect to the absorbed power) was 18mW. The laser was tunable from 1009 to 1081nm.
